Claims. (Cl.'221146) This invention relates to new and usefulimprovements in coin-controlled vending machines, and has for itsspecific object to control and secure in a fixed position the memberserving as a support for things or articles to be displayed for sale,whether these are toys, candy or the like, and without regard to whetherthe said member has the shape of a disk or a bowl.

As the construction is comparatively simple,

the cost of adding this improvement to the vending machines, nowcommonly known, would be insignificant.

With the above and other objects in view, this invention consists of thenovel features of construction, combination and arrangement of parts,hereinafter fully described, claimed and illustrated in the accompanyingdrawing forming part of this application, and in which similarcharacters of reference indicate corresponding parts in all views, andin which:

Figure 1 is a side elevational view of my device;

while Figure 2 is a top plan View of same; and Figure 3 shows amodification of said device. Referring more particularly to the drawing,which illustrates a vending machine in part only, or to the extent ofshowing my improved device in relation thereto, 10 indicates a rotatingmember, in this instance a bowl, divided into interchangeablecompartments 11, by means of a system of removable partitions 32, whichare inserted and held between the lugs 33 and 34, respectively. The saidmember is enclosed in a casing 12, of the usual kind, in front of'whichis the ordinary push-button 13, which is connected to a rod 15, and heldin normal or inactive position by means of a coiled spring 14. The saidrod has at its inner end provided means usually in form of a rubber pad,for rotating the said member 10, for the purpose of bringing the articleselected upon the said member in front of the usual discharge opening.

When a coin is deposited in the slot of the vending machine the usualoperation, or relative movements of the mechanisms, takes place with theresult that the gripping members 16 are lowered and made to pick up thearticle selected from the member or bowl 10, for delivery to thepurchaser, or depositor of the coin.

However, it is essential that during such latter movement the member, orbowl, 10 is made to stand still, or becomes arrested, so that no furtherturning movement can be imparted to the said bowl by means of operatingthe outside knob 13.

This is accomplished by adding to the usual mechanism, the following newfeatures or elernents:

An eccentric disk 17 is mounted upon a rotating rod 18, which forms partof the now commonly used mechanism; the said disk 17 is made to operatea lever 19, terminating in a weighted portion 19, and pivotally arrangedupon an upright, as shown at 20; the said lever actuating in turn an arm21, that engages the member or bowl 10 by means of a gearing 22 formedupon the edges of the latter, and thereby secures a stop of said bowl.It is evident that such arresting movement of the bowl must be timed toco-operate with the action of the gripping members 16.

Thus, once the mechanism of the vending ma- 0 chine is set in motion bydepositing a coin, the member, or bowl, 10 will stand still during themechanical function of the gripping members 16.

A modification of my actual device is shown in Figure 3, where aneccentric disk23 is mounted 5 upon a rotating rod 18, as shown in Figure1; the said disk is made to operate a plunger 24, which is guided in atube 25 secured to a framework 26, the latter being fastened to .thebottom of the casing, as shown at 27; the upper end of the said plungeris in turn connected to an arm 28 of a bifurcated lever, which ispivotally mounted, as shown at 29, and which has its other arm 30adapted to engage with a gearing 22,- formed upon the edges of the bowll0, and arrest the latter, when the said plunger is acted upon by theeccentric disk 23. When the said plunger is not pushed upwardly by thesaid disk, the coiled spring 31, mounted upon the upper end of theplunger 24, will urge the latter downwardy with 9 the result that thearm 30 becomes disengaged from the gearing 22 of the member or bow 10,and the latter will again be free to move.

This arrangement naturally again presupposes a proper timing for thesake of securing an exact 9 co-operation of the different elements, asformer- 1y stated.

It is obvious that changes may be made in the form, construction andarrangement of the several parts, as shown, without departing from thespirit of the invention, and well within the scope of the appendedclaims, and I do not therefore desire to limit myself to the exactconstruction and arrangement, shown and described herein.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is: r

1. In a coin-controlled vending machine, a centrally mounted, rotatingbowl, interchangeable partitions arranged in the latter, and means forsecuring said partitions in place, a gearing tainer, manually operablemeans for adjusting the position of the container, and automaticgrappling means for picking up and removing commodities located in thecontainer.

3. Ina vending machine, an article container, grappling means forgrasping articles located in the container which means is adapted tomove the said bowl in timed coin a fixed path to a point Within thecontainer, and manually operable means for adjusting the position of thecontainer, whereby certain articles in the container may be placed inposition to be grasped by the grappling means.

4. In a vending machine, an enclosed cabinet, an adjustable commoditycontainer mounted in the cabinet, means extending externally of thecabinet for moving the container in circular directions, and means inthe cabinet for grasping and removing commodities located in thecontainer.

5. In a vending machine, an enclosed cabinet, an adjustable commoditycontainer mounted in the cabinet, means extending externally of thecabinet for moving the container in circular and horizontal directions,and means in the cabinet for grasping and removing commodities locatedin the container.
